Design of a rotary reactor for chemical-looping combustion. Part 1: Fundamentals and design methodology
(Elsevier, 2013-12)Chemical-looping combustion (CLC) is a novel and promising option for several applications including carbon capture (CC), fuel reforming, H2 generation, etc. Previous studies demonstrated the feasibility of performing CLC ... -
Design of a rotary reactor for chemical-looping combustion. Part 2: Comparison of copper-, nickel-, and iron-based oxygen carriers
(Elsevier, 2013-12)Chemical-looping combustion (CLC) is a novel and promising option for several applications including carbon capture (CC), fuel reforming, H2 generation, etc. Previous studies demonstrated the feasibility of performing CLC ... -
Design of a spaceflight biofilm experiment
(Elsevier BV, 2018-04)Biofilm growth has been observed in Soviet/Russian (Salyuts and Mir), American (Skylab), and International (ISS) Space Stations, sometimes jeopardizing key equipment like spacesuits, water recycling units, radiators, and ... -
Design of a Spherically Actuated Human Interaction Robot Head
(ASME International, 2012-04)This paper presents the development of a mechanism for actuating a sphere holonomically about 3 degrees of freedom (DOF). The target application is a robot head for mounting inside a vehicle to provide a driver with ... -
Design of a Surgical Port for Minimally Invasive Beating-Heart Intracardial Procedures
(ASME International, 2011-03)Direct-access, minimally invasive, beating-heart intracardial procedures have the potential to replace many traditional surgical procedures requiring cardio-pulmonary bypass as long as micro-emboli are prevented from ... -
Design of a Thermally-Actuated Gas Lift Safety Valve
(ASME International, 2011-06)Gas-lifted oil wells are susceptible to failure through malfunction of gas lift valve assemblies (GLV). One failure mode occurs when the GLV check valve fails and product passes into the well annulus, potentially reaching ... -
Design of a Wireless, Passive, Single-Use Emergency Call System
(ASME International, 2010-11)In order to improve patient access to nurses during emergencies, a wireless wrist-mounted call button system was developed. The goal of this project was to create a simple, easy-to-use system that features a completely ... -
Design of Agricultural Waste Charcoal Cooking Fuel for Developing Countries
(American Society of Mechanical Engineers (ASME), 2013-08)Charcoal made from agricultural waste (AWC), intended for use in developing countries, has the potential to be a cooking fuel with health, economic, and environmental benefits. Investigations were undertaken to integrate ... -
Design of an Ankle Rehabilitation Device Using Compliant Mechanisms
(ASME International, 2011-01)In this paper, we present the design, analysis, and testing of an ankle rehabilitation device (ARD), the purpose of which is to improve the efficacy of ankle joint complex (AJC) injury diagnosis and treatment. The ARD ... -
Design of an efficient terahertz source using triply resonant nonlinear photonic crystal cavities
(Optical Society of America, 2009-10)We propose a scheme for efficient cavity-enhanced nonlinear THz generation via difference-frequency generation (DFG) processes using a triply resonant system based on photonic crystal cavities. We show that high nonlinear ... -
Design of an Electric Motor Transmission System Without Friction Synchronization
(ASME International, 2019-08)Copyright © 2019 ASME. This paper investigates the design of a new transmission system without a friction synchronizer for high-performance hybrid vehicles. Manual and automated manual transmission systems traditionally ... -
Design of an Integrated Cotton Picking System for Small-Scale Indian Agriculture
(ASME International, 2017-08)India, the world's largest producer of cotton, contains more than 4 million cotton farms that are less than 5 acres. These farms are incapable of large-scale mechanization due to small farm size and irregular farm shape. ... -
Design of an Organic Simplified Nuclear Reactor
(Elsevier BV, 2016-03)Numerous advanced reactor concepts have been proposed to replace light water reactors ever since their establishment as the dominant technology for nuclear energy production. While most designs seek to improve cost ... -
Design of an overmoded W-band TWT
(Institute of Electrical and Electronics Engineers, 2009-08)We report on the design and cold test validation of an overmoded TWT capable of producing power in excess of 100 Watts in the W-band and above. The TWT operates in the TM31 mode of a rectangular cavity and has transverse ... -
